Frequently Asked Questions
How do I convert Fahrenheit to Celsius?
°C = (°F - 32) × 5/9. For 72°F: (72 - 32) × 5/9 = 22.2°C. Quick mental math: subtract 30, then divide by 2 (gives approximate result). The converter provides exact values instantly.
What is room temperature in both scales?
Comfortable room temperature is 68-72°F or 20-22°C. Thermostat settings: 68°F = 20°C (energy-saving), 72°F = 22.2°C (comfortable), 78°F = 25.6°C (warm). The converter helps set international thermostats.
What are common cooking temperatures in both scales?
Low oven: 300°F = 149°C. Moderate: 350°F = 177°C. Hot: 400°F = 204°C. Very hot: 450°F = 232°C. Broil: 500°F = 260°C. The converter is essential for following recipes from different countries.
What is a fever temperature in Fahrenheit and Celsius?
Normal body temperature: 98.6°F / 37°C. Low-grade fever: 99.1-100.4°F / 37.3-38°C. Fever: 100.4°F+ / 38°C+. High fever: 103°F+ / 39.4°C+. Seek medical attention above 104°F / 40°C.
How was the Fahrenheit scale created?
Daniel Fahrenheit set 0°F as the coldest temperature he could create (brine solution), 32°F as water's freezing point, and 96°F as body temperature (later refined to 98.6°F). The scale was established in 1724.
